My budget is flexible but i was thinking around $100-$200 for the Gpu and about $50-$100 for the power supply

You have a nice budget try investing in a new system,
However here is what you should go with:

I think that optiplex 755 had smaller cases so in this case here is the perfect card for it:

Its small and very nice at price to performance and a good pair with a system like that
but if the case is big enough get this card instead:

Now for the PSU,

Also why would i need to invest in a new machine, this computer is a beast at games now with its gt 740 (sorry forgot to mention that above) so i don't see why i need to invest
